CVE-2026-78426 (GCVE-0-2026-78426)
Vulnerability from nvd – Published: 2026-09-17 09:28 – Updated: 2026-09-17 12:40

Title
Logout bypass via alternate JWT spelling
Summary
The NeuVector JWT verifier accepts noncanonical Base64URL encodings of the same RSA signature field. An attacker holding a valid JWT that has not expired, but was logged out of NeuVector, can continue using the non-expired token with equivalent spelling of the RSA signature field until the token validity expires.
